Rivers are like lazy kids who keep changing their paths. When they flow, they carry sand and rocks with them, which helps them dig deeper into the ground or pile up on one side. Over time, this makes rivers bend, widen, or even split in two, it's all part of a big game that lasts for thousands of years.
Why It Happens
Rivers pick up speed when they flow down hills and slow down when they reach flat areas. When they're fast, they carry more rocks and sand with them, which helps them dig out new paths. When they're slower, the heavy stuff settles at the bottom or piles up on the sides, this changes how a river looks over time.
The Result
Eventually, these changes can make rivers look totally different from what they were in the beginning. They might even create new lakes or change where they meet the sea.
Examples
- A river might start as a narrow stream but widen into a wide river over time, like a child growing up into an adult.
- Rivers can create new lakes when they cut through land between two bends, turning them into ponds.
- Sometimes, a river changes direction entirely, leaving behind a dried-up riverbed that people no longer use.
